Red tide is a common name for a phenomenon also known as an algal bloom (large concentrations of aquatic microorganisms) , an event in which estuarine, marine, or fresh water algae accumulate rapidly in the water column and results in discoloration of the surface water. It is usually found in coastal areas.
Algal blooms that cause red tide are primarily caused by the rapid growth of phytoplankton, particularly species like Karenia brevis. These blooms can be triggered by factors like nutrient pollution from human activities, warm water temperatures, and calm sea conditions that allow the algae to flourish. The resulting high concentrations of algae can release toxins that harm marine life and impact human health.

Algal bloom is the process where algae turns the color red. This happens when there is a sudden burst of heat from the sun and the nutrients in the earth below the sea rise into the algae and some of the nutrients turns the algae red which in turn, makes the sea looks like it is the color red.
The Red Sea is named after a type of algae called Trichodesmium erythraeum. This algae can form large blooms in the water, giving the sea a reddish-brown hue.
Avoiding red tide involves staying away from affected areas, abstaining from eating contaminated seafood, and being mindful of any respiratory issues that may arise from exposure to red tide toxins. Monitoring local advisories and being cautious of discolored water or dead fish can help prevent encountering red tide.
Algal can cause "red tides". Specifically algal blooms.

Algal blooms and red tides are both caused by the rapid growth of certain types of algae, often due to nutrient pollution in water. This overgrowth can lead to dense populations of algae, causing discoloration of the water and potential harm to aquatic life by depleting oxygen levels. Red tides specifically refer to algal blooms that produce toxins that can be harmful to marine organisms and humans.
The most recent red tide event occurred in Florida in 2021, impacting the Gulf of Mexico and causing environmental and economic concerns due to the harmful algal blooms.

Red tide is an example. When severe enough they become harmful algal blooms which do damage to life beneath them in the water column.
Dinoflagellates in the phylum Dinoflagellata are responsible for causing red tides. These harmful algal blooms can produce toxins that contaminate shellfish when ingested, leading to a condition known as paralytic shellfish poisoning.

Signs of red tide include discolored water, fish kills, strong odor, respiratory irritation in humans, and dead or stranded marine animals. It can also impact shellfish populations and lead to closures of shellfish harvesting areas.
